United's strength in depth shines through

Keeper Sergio Romero made his first start since United's Europa League final triumph against Ajax in May, while Michael Carrick captained the team on his first appearance of the season.

Rashford and Juan Mata were the only two players who started the 4-0 win over Everton last Sunday to make the team, but there was still no starting place for Luke Shaw.

Since returning from injury in last season's Community Shield, the former Southampton defender has started just 17 of 72 games.

Shaw came on at the start of the second half by which time United were 3-0 ahead.

Luke Shaw came on as a substitute - his first competitive action since April

It was a night of positives for Jose Mourinho, although the United boss is likely to have been unimpressed when 21-year-old substitute keeper Joel Castro Pereira dropped the ball allowing Dyer to score with a few seconds to play.

Burton's changes puzzle Mills

Burton, 19th in the Championship table, face QPR in the league on Saturday, yet Nigel Clough's decision to make nine changes puzzled at least one pundit.

"A lot of these Burton players will never get a chance to play at Old Trafford again," said former England defender Danny Mills on BBC Radio 5 live before the tie.

"They are coming here knowing however many changes Manchester United make, United will still be unbelievably strong. Will Burton win the Carabao Cup? No.

"The manager is probably thinking 'do my players need an extra game?'

"However, those Burton players who have been rested are missing out on the one opportunity to play against a Jose Mourinho side at Old Trafford.
